MECHAIilISM FOR ACTUATING MUSIC-ROLLS IN PNEUMATIC PLAYERS.

Specification. of Letters Patent.

Application filed June is, 1911. Serial in piano players.

In the accompanying drawings which illustrate one emhodinicntof myinve1 1tion,-- Figure l is a front view of the spool box of a piano player, and of my improved transmission mechanism; Fig. '2 is at side View, taken from the right, of the mechanism shown in Fig. .2; and Fig. 3 is a. top view on line of Fig. l.

The spool box is shown at A, and contains the receiving spool B carried by the receiving shaft 5, and the music roll shafts or spindles c and c which-carry the music roll spool C. The perforated music sheet 0 passes in the usual way from the spool C over the tracker her T to the receiving spool B.

The shafts or spindles o and c are journnled in and extend through the end. wall of the spool box A. A pinion is secured fast to spindle 0 on the outer side of the spool box. In mesh with pinionc is an intermediate gear (Z for driving pinion c 'jourhuled on a stud cl on the outer wall of spool box A. The receiving spool shaft Z) is provided with a driving gear 6 on the outer side of thev spool box for turning the receiving spool shaft 5.

Inv the space between the intermediate gear (Z and the gear e is the driving pinion f, fixed to the driving shaft 9'. The shaft 9 is provided with s universal oint 9, so that the pinion f may be shifted into engagement with either the gear d or the gear 0, and

out of engagement with the other. The shaftg is connected with a motor (not shown) which may he of usual construction. The end of shaft 9, near the pinion f, is supported by a collar or hearing it, which is carried by lever Lever Z is pivoted on a. bracket j, secured to the spool box, and is actuated by the lever arm is, The bracket j "is made with two arms Z, for holding set screws Z, which form adjustable stops to limit the movement of lever 2, and consequently of pinion f.

The lever arm is is actuated by a rod m, mounted to slide in the spool box, and the manually operated shifting lever When lever n is thrown to the right, as shown in Fig, 1, driving pinion f will he swung downward into mesh with gear e. 'lThe receiving spool B will then be rotated by the driving shaft to wind the music sheet 0 from spool C on to spool When the music sheet is to be rewound on spool C, lever n is shifted to the'leit, and pinion f is thereby shifted out of mesh with gear 6 and into mesh with gear (Z.

Festened to lever i are the spring arms 0 each carrying at its end a pad 79 of felt or other suitable material, to act as a brake when pressed against the driving gear. l-Vhen the lever 1 is swung downward to shift pinion f into mesh with. gear 6, the upper brake 9 will he yieldingly applied to gear (Z, and at the same time the pressure of the lower hrshep against gear 6 will. be relieved This will permit the receiving shett Z) to he turned easily from the driving shaft, and the upper he will prevent the spool C, which for the me being is turning idly, from spinning or uni'olling the paper faster then it is telren up by the receiving spool B. Similarly, when lever z is swung upward to shift pinion into mesh with gear (3, the pressure of theupper lornke 39 against gear at will be relieved, and the lower brake p will be yieldingly applied to gear 6.

I claim:
